BYU engineers conceive disc replacement to treat chronic low back pain

13.06.2012
Technology licensed by BYU to Utah-based Crocker Spinal Technologies
In between the vertebrae of the human spine are 23 Oreo-sized, cartilage-filled discs that hold the vertebrae together and allow for spine movement.

While the discs are critical for movement, they can become the source of back pain when they degenerate or herniate – a major health problem that affects 85% of Americans and drains the U.S. economy to the tune of $100 billion every year.

A new biomedical device to surgically treat chronic back pain – an artificial spinal disc that duplicates the natural motion of the spine – has been licensed from Brigham Young University to a Utah-based company.

The artificial disc was conceived by engineering professors Anton Bowden and Larry Howell and BYU alum Peter Halverson. It will be developed to market by Crocker Spinal Technologies, a company founded by BYU President’s Leadership Council member Gary Crocker and headed by BYU MBA graduate David Hawkes.

The BYU researchers report on the mechanism’s ability to facilitate natural spine movement in a study published in a forthcoming issue of the International Journal of Spine Surgery.

“Low back pain has been described as the most severe pain you can experience that won’t kill you,” said Bowden, a BYU biomechanics and spine expert. “This device has the potential to alleviate that pain and restore the natural motion of the spine – something current procedures can’t replicate.”

Currently, the most common surgical treatment for chronic low back pain is spinal fusion surgery. Fusion replaces the degenerative disc with bone in order to fuse the adjacent segments to prevent motion-generated pain.

Unfortunately, patient satisfaction with fusion surgery is less than 50 percent.

The solution researched by the BYU team, and now being developed by Crocker Spinal Technologies, consists of a compliant mechanism that facilitates natural spine movement and is aimed at restoring the function of a healthy spinal disc.

Compliant mechanisms are jointless, elastic structures that use flexibility to create movement. Examples include tweezers, fingernail clippers or a bow-and-arrow. Howell is a leading expert in compliant mechanism research.

“To mimic the response of the spine is very difficult because of the constrained space and the sophistication of the spine and its parts,” Howell said. “A compliant mechanism is more human-like, more natural, and the one we’ve created behaves like a healthy disc.”

Under Howell’s and Bowden’s tutelage, BYU student-engineers built prototypes, machine tested the disc and then tested the device in cadaveric spines. The test results show the artificial replacement disc behaves similarly to a healthy human disc.

“Putting it in a cadaver and having it do what we engineered it do was really rewarding,” Howell said. “It has a lot of promise for eventually making a difference in a lot of people’s lives.”

Halverson, who was lead author on the International Journal of Spine Surgery study, has since earned his Ph.D. from BYU and taken a position at Crocker Spinal Technologies, which will likely begin international sales distribution as early as next year.

“Fusion, which is the current standard of care for back pain, leaves a lot to be desired,” said Hawkes, president of Crocker Spinal Technologies. “Disc replacement is an emerging alternative to fusion that has the potential to make a significant difference in the lives of millions.

“BYU’s innovation is a radical step forward in the advancement of disc replacement technology. It is exciting to be a part of this effort and a delight to work with such talented, wonderful people,” he said.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
